Alright, firstly, alot of people get annoyed with people asking this question but i'l giuve you a short answer.
Laptop screens are fine to use, however they can become expensive and fiddly. Ther are lots and lots of users on this forum that use Laptop screens.
In order to do so, you will need:
A compatible controller
A compatible backlight inverter
A suitable hirose cable (connects LCD to controller)
Just a basicx insight. This has all been mentioned on previous posts so it may pay to do a search.
